drm/simpledrm: Support virtual screen sizes

2021-11-11T11:06:58Z

Add constants for the maximum size of the shadow-plane surface size. Useful for shadow planes with virtual screen sizes. The current sizes are 4096 scanlines with 4096 pixels each. This seems reasonable for current hardware, but can be increased as necessary. In simpledrm, set the maximum framebuffer size from the constants for shadow planes. Implements support for virtual screen sizes and page flipping on the fbdev console. v3: * use decimal numbers for shadow-plane constants (Noralf) Signed-off-by: Thomas Zimmermann Acked-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20211110103702.374-9-tzimmermann@suse.de

drm/simpledrm: Enable FB_DAMAGE_CLIPS property

2021-11-11T11:06:58Z

Enable the FB_DAMAGE_CLIPS property to reduce display-update overhead. Also fixes a warning in the kernel log. simple-framebuffer simple-framebuffer.0: [drm] drm_plane_enable_fb_damage_clips() not called Fix the computation of the blit rectangle. This wasn't an issue so far, as simpledrm always blitted the full framebuffer.

drm/format-helper: Streamline blit-helper interface

2021-11-11T11:06:57Z

Move destination-buffer clipping from format-helper blit function into caller. Rename drm_fb_blit_rect_dstclip() to drm_fb_blit_toio(). Done for consistency with the rest of the interface. Remove drm_fb_blit_dstclip(), which isn't required.

drm/simpledrm: Use offset-adjusted shadow-plane mapping

drm: simpledrm: fix a potential NULL dereference

2021-05-15T12:04:42Z

The drm_format_info() function returns NULL if the format is unsupported, but the simplefb_get_validated_format() is expected to return error pointers. If we propagate the NULL return then it will lead to a NULL dereference in the callers. Swap the NULL and trade it in for an ERR_PTR(-EINVAL).

drm: simpledrm: Fix use after free issues

2021-05-13T14:00:54Z

There are two occurrances where objects are being free'd via a put call and yet they are being referenced after this. Fix these by adding in the missing continue statement so that the put on the end of the loop is skipped over.
